摘要： In an outboard motor steering control system having a plurality of outboard motors each adapted to be mounted on a stern of a boat by a shaft to be movable by an actuator relative to the boat and each having an internal combustion engine to power a propeller, a desired steering angle of each outboard motor is determined individually based on detected engine speed and rotation angle of a steering wheel, and the operation of the actuator is controlled based on the determined desired steering angle, thereby improving both straight course-holding performance and turning performance by regulating the relative angles between the outboard motors in response to the cruising conditions of the boat.

摘要： In an outboard motor steering system, the engine speed is detected as a value indicative of the speed of the boat and a current value for operating a steering hydraulic cylinder is determined to decrease with decreasing engine speed. The current value can therefore be determined in accordance with the steering load to reduce electric power consumption. Moreover, owing to the fact that the drive current is determined as a function of steering load, it is possible to prevent the output of the cylinder from becoming excessive relative to the steering load, thereby ensuring that the steered angle tracks a desired steering angle with good accuracy.

摘要： In an engine speed control system for an outboard motor, overrev prevention control is implemented which determines whether the engine overrevs by comparing the detected engine speed and a desired speed and responds to a determination that the engine overrevs (in which case the cause of the engine speed increase is probably reduced load caused by sucking in of air and/or exhaust gas by the propeller) by driving an electric throttle motor in the direction of reducing the throttle opening, thereby lowering the engine speed to the desired speed. Owing to this configuration, the problem of decline in thrust owing to intake of air and/or exhaust gas by the propeller can be quickly overcome irrespective of operator skill, thereby improving power performance and steerability.

摘要： An outboard motor engine speed control system includes two outboard motors, sensors which detect a travel speed of the boat and the engine speeds of the outboard motors, and a controller which controls the engine speeds of the outboard motors to be synchronized with a highest one of the detected engine speeds when the boat travel speed is equal to or higher than a predetermined value, while controlling the engine speeds of the outboard motors to be synchronized with a lowest one of the detected engine speeds when the boat travel speed is lower the predetermined value. The operations involved in engine speed control of the outboard motors mounted on the boat are thereby simplified and the feel of operation is enhanced.

摘要： An outboard motor operating system, includes a shared switch for inputting operation instructions to either a steering (hydraulic) cylinder for steering an outboard motor or a PTT unit for regulating the tilt/trim angles of the outboard motor. The system also includes a first group of signal lines connected to the steering cylinder, a second group of signal lines connected to the PTT unit, and a third group of signal lines connected to the shared switch. The operating system also includes a selector switch for connecting either the first or second group of signal lines to the third group of signal lines. Thus, a shared operating system is provided for inputting operation instructions to the steering cylinder and PTT unit, and the destination of the instructions is made selectable, enabling a reduction in the number of components and a reduction in the amount of space needed for installing the operating system on the boat.

摘要： In an outboard engine system, an inertia force a generated longitudinally by a piston 14 is countervailed by an inertia force b generated by a crankshaft 15, and inertia forces c and d subsidiarily laterally generated vibrate a body of the outboard engine system laterally about a phantom center point C of vibration. At this time, an elastomeric member 74 resiliently supporting the system body on a hull has a rigidity in a tangent direction (in the direction of L3) about the phantom center point C of vibration, which is set to be lower than a rigidity in a radial direction (in the direction of L2) about the phantom center point C of vibration. Therefore, the lateral vibration is reduced effectively due to the lower rigidity of the elastomeric member 74. Thrusts e and f generated by a propeller and acting in a longitudinal direction (in the direction of L1) are transmitted to the hull through the elastomeric member 74. However, the rigidity of the elastomeric member 74 in the longitudinal direction is set to be higher and hence, the thrusts e and f can be transmitted effectively to the hull.

摘要： In an outboard motor shift control system having a shift mechanism including a forward gear, a reverse gear and a clutch and an electric motor moving the clutch to engage with one of the forward and reverse gears or to disengage it therefrom, current supplied to the motor is detected, and completion of shift change is discriminated based on the detected current. With this, it becomes possible to detect completion of the shift change accurately, without being affected by shift mechanism aging and manufacturing variances.

摘要： An outboard motor steering system includes a hydraulic fluid supply mechanism connected to the steering hydraulic cylinder to supply hydraulic fluid thereto disposed in a space formed between the stern brackets and the swivel case. In other words, since the hydraulic fluid supply mechanism is incorporated into the outboard motor as a unit, the structure can be made simpler than that of the related art and the number of parts in the entire system can be reduced and moreover the work of installation into the boat's hull can be simplified. Also, operating efficiency is improved for an electric motor serving as the source of driving force for a hydraulic pump that supplies hydraulic fluid to the hydraulic cylinder used for steering, and power consumption is reduced.
